METHOD AND APPARATUS FOR TRANSMISSION AND RECEPTION OF CYCLIC SUBCARRIER SHIFT TRANSMIT ANTENNA DIVERSITY

摘要

PURPOSE: A method and an apparatus for transmitting and receiving transmission antenna diversity using cyclic subcarrier shift are provided to use multi antennas while keeping a PAPR(Peak to Average Power Ratio) low, thereby transmitting data in a form for providing transmission diversity. CONSTITUTION: A DFT(Discrete Fourier Transform) spread unit(110) performs DFT on a modulated symbol. The spread unit generates frequency domain symbols. A resource mapper(120) maps each frequency domain symbol on a plurality of frequency domain streams. Cyclic shift units cyclically transits each frequency domain stream. Signal transmission units transmit the time domain streams.
